I am building some new 4 x 100 Watt LED luminaires supplied by 35 Volts DC @ 3 Amps. I'll LED you know my experiences in a few weeks.... I will try using a voltage stabilizer first. If the terminal voltage varies much with temperature a current driver approach may be necessary.
These 10x10 LEDS start at 28 Volts and draw full current at 37 Volts, and create an awful lot light. Regards, Ing.
